lam-runtime

LAM runtime environment for executing parallel programs
LAM (Local Area Multicomputer) is an open source implementation of the
Message Passing Interface (MPI) standard.
.
Some enhancements in LAM 6.3 are:
o Added the MPI-2 C++ bindings package (chapter 10 from the MPI-2
standard) from the Laboratory for Scientific Computing at the
University of Notre Dame.
o Added ROMIO MPI I/O package (chapter 9 from the MPI-2 standard)
from the Argonne National Laboratory.
o Pseudo-tty support for remote IO (e.g., line buffered output).
o Ability to pass environment variables through mpirun.
o Ability to mpirun shell scripts/debuggers/etc. (that eventually
run LAM/MPI programs).
o Ability to execute non-MPI programs across the multicomputer.
o Added configurable ability to zero-fill internal LAM buffers
before they are used (for development tools such as Purify).
o Greatly expanded error messages; provided for customizable
local help files.
o Expanded and updated documentation.
o Various bug fixes and minor enhancements.
